Determine if the following argument is valid or invalid. State if valid or invalid. If it rains, I can not go fishing. It did not rain. Therefore, I can go fishing. Is the argument a Fallacy of the inverse,? a Fallacy of the converse? or is the argument Fallacy of the inclusive or?
Determine whether the argument is valid or invalid. No A are B, all B are C, and no C are D. Thus, no A are D. This argument is because
Prove the validity of the following argument using direct proof.
what is an example of an invalid argument and why it is invalid?
Instructions: For each argument below, evaluate the truth of each premise (write “true,”“false,” or “questionable”). Then evaluate the argument’s support (write “valid” or“invalid,” and briefly explain why). Finally, determine the overall quality of theargument (write “sound” or “unsound”), and briefly explain whySAMPLE: P1) Some dads have a beard.P2) All bearded people are mean.C) Some dads are mean.Truth of premise 1: trueTruth of premise 2: questionable (“mean” is subjective)(true, false, or questionable)Support: valid(valid or invalid)Why: the premises establish that bearded dads are mean,so some dads (the ones with beards) are meanOverall: unsound(sound or unsound)Why: fails the truth test -- premise 2 is not true1.

← A dietician is planning a snack package of fruit and nuts. Each ounce of fruit will supply zero units of protein, 3 units of carbohydrates, and 2 units of fat, and will contain 40 calories. Each ounce of nuts will supply 3 units of protein, 1 unit of carbohydrate, and 4 units of fat, and will contain 50 calories. Every package must provide at least 6 units of protein, at least 8 units of carbohydrates, and no more than 16 units of fat. Find the number of ounces of fruit and number of ounces of nuts that will meet the requirement with the least number of calories. What is the least number of calories? Let x be the ounces of fruit and y be the ounces of nuts. What is the objective function that must by minimized? z- 40 x+ 50 y The dietician should use ounce(s) of fruit and ounce(s) of nuts. These amounts will have a total of calories (Type whole numbers.)

Use symbols to write the logical form of the following arguments. If valid, iden- tify the rule of inference that guarantees its validity. Otherwise, state whether the converse or the inverse error has been made. If you study hard for your discrete math final you will get an A. Jane got an A on her discrete math final. Therefore, Jane must have studied hard.
